Non-blending macromolecule concrete and construction method thereof

Abstract

The invention belongs to the technical field of road engineering and particularly relates to a non-blending macromolecule concrete and a construction method thereof. The non-blending macromolecule concrete is prepared from the following components in percent by weight: 80-89% of aggregate, 8-15% of macromolecule material and 3-5% of additive. The construction method comprises the following steps of: selecting the aggregate with a material diameter of 0-0.5 mm, 0.5-3 mm or 3-30 mm according to a place to be used in a construction process; adding the selected aggregate and the additive to a die or a set place; and injecting the macromolecule material in the aggregate under pressure of 4-10 Mpa, and then curing for 15-25 minutes, so that the construction of the non-blending macromolecule concrete can be completed. According to the non-blending macromolecule concrete provided by the invention, the macromolecule material is used as an adhesion agent, so that the non-blending macromolecule concrete has the advantages of low production cost, simple preparation and construction process, wide construction condition, high firmness and durability, and simple last-stage maintenance. The non-blending macromolecule concrete can be used for buildings in a special environment, the road engineering, maintenance engineering, underground engineering and the like.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a non-mixing polymer concrete with low production cost, simple proportioning and construction technology, wide construction conditions, firmness and durability, and simple post-maintenance and a construction method thereof. Background technique [0002] Concrete is one of the most important civil engineering materials in contemporary times and is widely used in industries such as houses and bridges. There are two types of traditional concrete, cement concrete used in buildings and road structures and asphalt concrete used in roads and urban road surfaces. Cement concrete is made of sand and gravel meeting the gradation requirements as aggregate, cement as a binder, and a certain amount of additives are added; asphalt concrete is made of sand and gravel meeting the gradation requirements as aggregate and asphalt as a binder. , And add a certain amount of mod...

AI Technical Summary

Problems solved by technology

Both cement concrete and asphalt concrete have disadvantages such as complex proportioning, special mixing and transportation equipment are required, and the finished concrete after mixing must be applied in time; cement concrete or asphalt concrete is first combined with aggregates such as sand and gravel and cement or asphalt. Mix and shake, make cement concrete or asphalt concrete, and then transport it to the construction site, pour it into a mold or spread it on the roadbed to form buildings, road structures or asphalt pavement. The construction process is very complicated and troublesome, especially for asphalt concrete. Heating is required during the mixing process, which wastes resources and pollutes the environment, and the construction of cement or asphalt concrete is seriously affected by seasons, temperature and environment. In harsh environments, such as rain, snow, and strong wind It is difficult or even impossible to construct; cement or asphalt concrete is limited by the setting period, and should be used up within the setting period, otherwise the concrete will fail and must be discarded, seriously wasting resources and increasing construction costs; in addition, after the cement concrete construction is completed It takes a long time to form strength, which requires a long health preservation period, and if there is an error during the health preservation period, it will seriously affect the service life in the later period, and the maintenance cost is high
